SASH HOLDER AND LOCK.

Application filedFebruary 2, 1921.

1 0 all. whom it may concern:

Be it known that 1, JAMES A. TEDDER, a citizen of the United States, residing at Princeton, in the county of Mercer and State of West Virginia, have invented certain new and useful Improvements in Sash Holders and Locks; and I. do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which. it appertains to make and use the same.

The invention. relates to windows and more particularly to means for securing the sash in the frame at any required adjusted position whether closed or partly open.

The invention has for its object the provision of single fastening means disposed in such relative position as to lock both sashes when closed or hold them in the required adjusted position so that tampering from the outside is prevented when either one or both sashes are partly opened for ventilation.

The invention consists of a lock ban slidably mounted in the frame at one side of the window opening, preferably in line with the meeting rails of the sashes, catches projecting laterally from the lock bar, corrugated or fluted strips let into rabbets in the side bars of the sashes to cooperate with the said catches and a lever having a cam slot to receive an extension, of the lock bar whereby to effect a sliding movement thereof into or out of engagement with the sashes.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention, it is to be understood. that in adapting the same to meet different conditions and. requirements, various changes in the form, proportion and minor details of construction may be resorted to Without departing from the nature of the invention.

Referring to the accompanying drawings forming a part of the specification,

Figure 1 is a sectional detail of a side portion of a window showing an application of the invention,

Figure 2 is a detail perspective view of the fastener, and

Figure 3 is a detail view in perspective of a portion of a sash showing the fluted or corrugated strip applied thereto.

Corresponding and like parts are referred to in the following description and desig- Serial No. 441,842;

nated in the several views of the drawings by like referencescharacters.

The window frame or casement is designated by the numeral 1 and receives the upper and lower sliding sashes 2 which are mounted therein in any approved manner. These parts may be of any construction and are illustrated to demonstrate the application of the invention.

The fastener embodies a lock bar 3 which is slidably mounted in a casing 4t, catches 5 projecting laterally from the lock bar in position to cooperate with corrugated or fluted strips 6 let into rabbets formed in the side bars of the sashes. The catches 5 may form a part of the lock bar or be separate therefrom and secured theretoin any substantial way. An extension 7 projects laterally from an end of the lock bar 3 and enters and cooperates with a cam slot 8 formed in the head of a lever 9 pivoted to one end of the casingt. The casing 4 may be constructed from an elongated sheet metal blank having longitudinal edge portions folded to form guide ways to engage edge portions of the lock bar and retain the latter in place and give direction thereto in its movement. Openings 10 are formed in the lock bar 3 in position to register with corresponding openings formed in the casing 4 to admit of placing the screws or fast/enings ll in position when securing the fastening after the same has been placed in proper position. An opening 12 is formed in an end of the casing 4 to receive the eX- tension 7, this being necessary because lever 9 is pivoted to the side of the casing opposite that receiving the lock bar. The lever 9 has a 180 movement and is made secure at the limit of its movement in either direction by a projection 13 of the casing 4 enteringa depression 14L of the lever 9. The pro jections 13 ride into and out of the depression 14 in a manner well understood.

The part 6 consists of a metal strip which is corrugated or fluted to provide a plurality of depressions for receiving the active ends of the catches 5, whereby to secure the sashes in the located position. The fluted or corrugated strips 6 act in the capacity of rack bars and. are let into rabbets formed in the side bars of. the sashes so as to be out of the way.

The fastener is preferably located in line with the meeting rails of the upper and.

lower sashes so as to lock both when closed; The fluted or corrugated strips 6' may be of any length depending upon the limit of adjustment at which the sash may be. secured when opened for ventilation. VVhe-n the window is closed both sashes are made secure by engagement of the catches 5 with the fluted strips 6 of the upper and lower sash. It will also be understood that the construction is such as to admit of independent adj ustmentofeither sash and in the adjusted position both sashes maybe locked by engagement of the catches 5 with the fluted strips 6 attached to both sashes; Movement of the lever 9 throws the lock bar to cause the catches 5 to clear both' sashes, hence either one or both of the sashes may be adjusted;

Movement of the lever 9 in an opposite direction pro ects the catches 5 into engagement with both sashes so as to lock the same upper and lower sashes slidably mounted in the frame, a casing applied to a side of the frame and havingan end vportion projecting outwardly therefrom and provided with an opening, a lock bar slidable in the casing and having lateral catches to engage the sashes and hold them in the required adjusted position and provided with a lateral extension passing through the opening in the project ing end portion of the casing, and alever pivoted to the side of the projecting end. portion of the casing opposite that receiving the lockbar and formed with a cam slot to receive the projectilig end ofthe' lateral extension of the said lock bar.

2. In awindow embodying a frame and upper and lower sashes slidably mounted in the frame, a casing applied to a side of the frame and having an end portion projecting outwardly therefrom andprovided with an opening,'a lock bar slidable in the casing and having lateral catches to'engage the sashes and hold the'min the required adjusted 7pc sition and provided with a lateral extension passing through the opening in the projecting end portion of the casing, a lever pivoted r to. the side of the projecting end portion of the casing opposite that receiving the lock bar and formed with a. cam slotito receive the projecting end of the lateral extension of the said lock? her, said leveradapted to swing upwardly and downwardly into vertical position, and inter-engaging means between the lever and projecting end of the casing to hold the lever in either of i extreme vertical positions.

In testimony whereof I aflix my signature in presence of two witnesses.

JAMES A. TEDDER.
